152. Maximum Product Subarray
Medium
17.6K
552
Companies
Given an integer array nums, find a
subarray
that has the largest product, and return the product.
The test cases are generated so that the answer will fit in a 32-bit integer.
Example 1:
Input: nums = [2,3,-2,4]
Output: 6
Explanation: [2,3] has the largest product 6.
Example 2:
Input: nums = [-2,0,-1]
Output: 0
Explanation: The result cannot be 2, because [-2,-1] is not a subarray.
Constraints:
1 <= nums.length <= 2 * 104
-10 <= nums[i] <= 10
The product of any prefix or suffix of nums is guaranteed to fit in a 32-bit integer.

- Q1. Internal Implementation of HashMap
- Ans.
HashMap is implemented using an array of linked lists to handle collisions.
HashMap stores key-value pairs in an array of linked lists
Hash function is used to determine the index of the array where the key-value pair will be stored
Collision handling is done by chaining, where multiple key-value pairs with the same hash value are stored in the same linked list
HashMap allows null keys and values
HashMap is not synchronized...
